I would if I didn't suspect it'll end up costing a lot more in the long run
trying to maintain umpteen different systems. What happens in 20 years time
when experts are needed for all of them and probably half the companies who
developed them have gone bust or been taken over and the new owners have
little incentive to spend money developing upgrades? At least with just one
system you could mitigate against that by creating your own in house team
but with 3 or 4? Unlikely.
applies to railways. It is perhaps why the EU have tried to push for
ERTMS which, in theory, offers a single system that is compatible
across borders and which can be supplied by a range of suppliers
without the "lock in" risk. Hasn't quite turned out like that though!!
Someone should have told them it involved non standard bananas. They'd have
had it all sorted in no time.
LOL!
If you think that ERTMS is "standard", then you will be sadly disappointed! At a recent signalling conference it was remarked that whilst there were many ERTMS schemes in Europe, there is German ERTMS, Dutch ERTMS, Spanish ERTMS, French ERTMS etc.!
Interoperable in theory, but not always in practice.....
I guess we needed plenty of standards so there are enough to go
around!
